Dear FSL experts,
After running single ICA for all subjects, I find that each subject has 1 IC which its time series is highly correlated with my interest stimulus. The stimulus design is not the same for all subject hence I cannot use tensor ICA. I want to maintain as much as information possible so I dont want to use concat ICA (since concat ICA will run in MNI space instead of subject space).
Here is what I got after my single ICA run:
-Time series of IC 1 of subject 1 is correlated with the event subject 1 lost the game -> zstats_threshold map of IC1 - subject 1
-Time series of IC 7 of subject 2 is correlated with the event subject 2 lost the game -> zstats_threshold map of IC7 - subject 2
.... so on.
I registered all the zstats_threhold map to MNI space but then stuck at finding a way to find common pattern of them.
Hence, is there any way in FSL that I can find common activation from all of the zstats_threshold maps ? I am thinking of average all the map and threshold the result at a specific threshold but I feel like it is not the correct way.
It would be very appreciated if anyone can give me any advice.
Best regards,
Khoi
